目的:为了解带蒂颊脂垫组织瓣的应用解剖及颊脂垫移植修复口腔内恶性肿瘤切除软组织缺损的愈合过程。方法：在尸体和活体观察的基础上总结颊脂垫组织瓣的解剖特点，并用于修复口腔颌面部恶性肿瘤切除后软组织缺损112例，还对颊脂垫移植后的愈合过程进行了组织学观察。结果：口腔内颊脂垫移植后6～8周完全上皮化，随访3个月至8年6个月，效果良好。结论：该组织瓣解剖恒定，易于切取，供区与受区邻近．可在同一切口内完成手术，供区隐蔽，不影响外观及功能，为修复口腔内软组织缺损提供了一种新的方法。
Objective: To understand the applied anatomy of pedunculated buccal fat pad flap and the transplantation of buccal fat pad to repair the healing process of oral soft tissue defect. Methods: The anatomic features of the buccal pad flaps were summarized on the basis of corpses and living body observations, and used to repair 112 cases of soft tissue defects after resection of malignant oral and maxillofacial tumors. The healing process after buccal fat pad transplantation was also performed. Observed. Results: Complete epithelialization was performed 6-8 weeks after buccal fat pad implantation in the oral cavity. Follow-up of 3 months to 8 years and 6 months showed good results. Conclusion: The tissue flap is anatomically stable and easy to cut. The donor site is adjacent to the receiving area. The operation can be performed within the same incision, providing concealment to the area, without affecting the appearance and function. It provides a new method for repairing soft tissue defects in the oral cavity.
